Monoorganylbismuth compounds

Compared with the chemistry of diorganylbismuth compounds R2BiX dealt with in Section 2.2.1, the chemistry of monoorganylbismuth compounds RBiX2 has not been studied in detail except for compounds which contain Bi-S bonds.

Monoorganylbismuth compounds with Bi-Se orBi-Te bonds (Table 2.14)... 

The most general method for the synthesis of diorganylbismuth compounds is the nucleophilic substitution of halo- or alkoxydiorganylbismuthines. Diorganylbismuth compounds are obtained by the action of an equimolar amount of an acidic compound on triorganylbismuthine. However, they are often aceompanied by a monoorganylbismuth or inorganic bismuth compound as a by-product.
